Gilberts Helps Rolls Royce Vent at Nuclear Facility

Ventilation Louvres - Air Distribution - Natural Ventilation - Ventilation Systems

Gilberts Rolls Royce

High performance at Rolls Royce’s Raynesway site is being maintained, in part through advanced ventilation.

Gilberts of Blackpool, the UK’s leading air movement specialist, has completed a major order for the supply of ventilation louvres and dampers, some up to 18m long, for one of the site’s manufacturing buildings. Gilberts undertook the project for Balfour Beatty Engineering Services and Virtus Consult.

The work is part of a £500m investment by Rolls Royce in regenerating the site, which is home to its core nuclear production capability.

Gilberts’ contract involved the manufacture and supply of its WHK75 high performance integrated louvres with VN75 dampers, plus 163 no associated mounting frames. The smallest louvre was 11.6m x 4.7m, with the largest 18.8m x 4.1m.

Observed Roy Jones, Gilberts’ Senior Technical Manager, “The nature of the site required that the ventilation delivered in terms of performance. Because we offer one of the highest specifications in the market, and have our own, in-house, manufacturing capability, we were uniquely placed to fulfill the brief with a solution that would perform in every way required of it.”

Gilberts WHK75 louvres feature a unique blade design to deliver optimum ventilation and weathering performance: a 50% free area ensures good airflow, enabling air volumes of over 1.5m³/s even with a pressure drop of 20Pa. For weather resistance, the system is proven to achieve 99.5% effective in screening/ exhaust applications, and 99% effective even with face velocities of up to 1m/sec.

All Gilberts’ systems are engineered to order, in the UK. Founded 50 years ago, privately owned Gilberts is unique in having its own, on-site (85,000ft²) manufacturing facility, producing engineered solutions, with an in-house test centre. Technical expertise is supported by bespoke software developed in partnership with the University of Strathclyde, addressing air movement and flow simulation/computation fluid dynamics.
